On-site treatment by bioremediation technology  (India)

Bioremediation is a cost effective, environmentally sustainable, safe and alternative technology for remediation of wastewater. The present work was aimed to evaluate the role of inoculated microalgae (Chlorella minutissima) in treating the municipal sewage wastewater flowing in 10 drains. The project mainly involved surveying and mapping of the drains, installation of dosing stations, installations of screens and construction of check dams at different locations along the drains. Bioremediation refers to the optimization of naturally occurring remediation processes carried out by living organisms that degrade, alter or remove toxic organic compounds. The application of bioremediation techniques is an alternative for the disposal of non- treated wastewater during crop irrigation; the efficiency of bioremediation techniques depends on a number of factors that should be considered when choosing a treatment that provides the water quality that meets the needs of crops. It is highly efficient for removing, transforming or degrading different types of contaminants found in wastewater, particularly using the mechanisms of phytoextraction and rhizo filtration to bioremediate/Phyto remediate the drains in order to reduce pollution level on recipient river systems. The project aims to not only bring down BOD/COD levels in the limits reduces obnoxious odor and H2S emission and substantially decreases mosquitoes and flies breeding and hence improves sanitation.
